RuntimeException在收到通知後拋出

Question

我在C＃Xamarin.Android項目上實施了推送通知，就像他們在官方Firebase文檔中一樣。

可以使用Firebase控制檯發送通知。現在我試圖從另一個C＃服務發送消息。設備監視器說，GCM消息已發送。

這裏是我的代碼。爲何會發生這種情況？

AndroidManifest.xml中

<application android:label="myApp" android:icon="@drawable/icon"> 
    <receiver android:name="com.google.firebase.iid.FirebaseInstanceIdInternalReceiver" android:exported="false" /> 
    <receiver android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver" android:exported="true" android:permission="com.google.android.c2dm.permission.SEND"> 
    <intent-filter> 
    <action android:name="com.google.android.c2dm.intent.RECEIVE" /> 
    <action android:name="com.google.android.c2dm.intent.REGISTRATION" /> 
    <action android:name="com.google.firebase.MESSAGING_EVENT"/> 
    <category android:name="${applicationId}" /> 
    </intent-filter> 
    </receiver> 

<service android:name=".MyFirebaseMessagingService"> 
    <intent-filter> 
     <action android:name="com.google.firebase.MESSAGING_EVENT"/> 
    </intent-filter> 
</service> 
</application> 

MyFirebaseMessagingService.cs

[Service] 
[IntentFilter(new[] { "com.google.firebase.MESSAGING_EVENT" })] 
public class MyFirebaseMessagingService : FirebaseMessagingService 
{ 
    const string TAG = "MyFirebaseMsgService"; 

    public MyFirebaseMessagingService() 
    { 
     Log.Debug(TAG, "Service called"); 
    } 
    public override void OnMessageReceived(RemoteMessage message) 
    { 
     string msg = message.GetNotification().Body; 
     Log.Debug(TAG, msg);  
    } 
}

我得到了它這個清單配置
